VCStack Feature
You can use the switches as standalone units or join up to four units with
the VCStack feature. The switches of a VCStack act as a single virtual
unit. They synchronize their actions so that switching operations (such as
spanning tree protocols, virtual LANs, and static port trunks) span across
all of the units and ports. Two advantages of stacks are:
You can manage multiple units simultaneously, which can simplify
network management.
You have more flexibility in how you configure some of the
features. For instance, a static port trunk on a standalone switch
can consist of ports from the same switch. In contrast, a static trunk
on a stack can have ports from different switches in the same
stack.
Note
This guide explains how to install switches as a stack with Virtual
Chassis Stacking (VCStack
™). For instructions on how to install the
devices as standalone switches, refer to the GS980MX Series
Installation Guide for Standalone Switches.
